RING-SPINNING FRAME.

SPECIFICATION forming part of Letters Patent No. 570,986, dated November 10, 1896.

Application led .l'uly 15, 1896.

To all whom iz? may concern,.-

Beit known that I, SAMUEL H. DUBo1s,'of Fall River, count-y of Bristol, State of Massachusetts, have invented an Improvement in Ring-Spinning Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to ring spinning frames, and has for its object the production of a simple and efficient stop-motion for the traverse mechanism, whereby the ring-rail may be stopped at any desired point of the traverse.

By means of my invention the operator can stop the motion of the ring-rail, when necessary, without waiting until the traverse is completed, as is now customary, andthe coni trol over the apparatus is thus greatly enlarged and perfected.

Figure 1 is a front elevation, partly broken out and in section, of a suiiicient portion of a ringspinning frame to be understoodwith my invention embodied therein. Fig. 2 is a top or planview of the parts shown in Fig. l, the ring and spindle rails being omitted; and Fig. 3 is a detail to be referred to of a part of the controlling device.

The ring-rail A,its lifting-rods A,the guiderails B and Bfor the lifting-rods, the rail B, supporting the spindles S, the draw-bar b3 of the builder mechanism, and the ad just-able hooked ear bs on said draw-bar are and may be of usual or Well-known construction.

The rock-shaft e4, mounted in depending brackets D on the guide-rail B, has secured thereto arms e5, provided With rolls to engage the ends of the lifting-rods A', substantially as in United States Patent No. 400,934, to which reference'may be had.

The arm e5, Figs. l and 2, is provided with a rearward extension el", having a foot-plate cl2, by means of which the operator can rock' the shaft e4 when the traverse mechanism is disconnected, and a stop, shown as a threaded stud-pin cl3, is extended through the part ew and held in adjusted position by suitable check-nuts e, the end of the stud engaging the rail B to limit the descent of the rin g-rail When controlled manually.

A counterpoise W is secured to the rockshaft e4 by an arm 615 to equalize somewhat Serial No. 599,241. (No model.)

the Weight of the ring-rail and parts carried therewith, and, as best shown in Fig. 2, I have rigidly secured to the rock-shaft between the arm e5 and counterpoise an upturned arm d, to the upper end of which is swiveled at d the rod CZX, which conveys the motion of the main rockshaft. e4 to the other similar shafts located in other parts of the frame, as is customary.

At one side of the arm d I have shown a stand d2, adjustably secured by a bolt d3, so that it may be moved toward or away from the rock-shaft, said stand being bifurcated at d4 to form ears Which support a horizontal pin d5 in ,parallelism with the rock-shaft e4, to be engaged by the hook o8 of the draw-bar b3, as shown in Figs. l and 2.

The draw-bar may be actuated in any usual manner, as,fo1 instance, bythe traverse mechanism shown in the patent referred to, the traverse mechanism forming no part of my invention.

A cam-block f, having a convexv surface f', is adjustably secured to the draw-bar by a suitable set-screwr fx, to be engaged and moved at times by a plate f2, slotted at f3 to permit the free passage therethrough of the draw-bar, and connected by a slot-and-bolt connection f4f5 to the upturned end h of a lever h. This lever h is loosely mounted on the rock shaft e4, to rock thereupon as a fulcrum, and it is extended at its opposite end at h2, a controlling-bar hX being pivoted thereto at h3. At its upper` end, which is within easy reach of the attendant, the bar is provided With a handpiece h4, by means of which said bar may be conveniently depressed. If now for any reason it is desired to stop the movement of the ring-rail at any point of the traverse, Without Waiting until the top or bottom of the movement is reached, the operator with his foot depresses the treadle e1", thus turning the rock-shaft back a slight distance in the direction of arrow 25, Fig. l. This movement of the rock-shaft relieves the pin d5 of the strain of the draw-bar hook bs, and the attendant with his hand at the same time depresses the controlling-rod hX, thereby lifting the plate f2 on the upturned end oflever 7l. As the plate is lifted it engages the camblock f, and acting on the face thereof tends to first press the hookb8 to the right, Fig. l,

IOO

to maintain it loose on the pin d, and when the draw-bar b3 is engaged by the bottom of the slotf 3 further upward movement of the plate will lift the draw-bar and hook entirely ont ofengagement with the pin d5 and maintain it disconnected. The rock-shaft eAL and parts moved therewith are thus disconnected from the traverse mechanism, and the operator can raise or lower the ring-rail A, as desired, by means of the treadle.

IVhen it is desired to connect the traverse mechanism again, the treadle is moved to bring the pin and draw-bar hook into engagement, at such time the controlling bar 71X and lever 7L beingin norma-l position. (Shown in Figs. 1 and 2.)

.The cam-block f and the cooperating plate and lever 7L form a releasingdevice for the draw-bar hook, manually controlled by or through the bar LX, and the treadle ew man ually controls the position of the rock-shaft el and parts operatively connected therewith.

My invention is not restricted to the precise construction and arrangement herein shown, as the same may be modified in various particulars without departing 'from the spirit and scope of my invention.

Having fully described myinvention, what I claim, and desire to secure by Letters Patent, is-

l. In a ring-spinning frame, the ring-rail, means, including a rocker-arm provided with a pin, to traverse said rail, and a reciprocating hooked draw-bar to normally engage the pin, combined with independent means to move the rocker-arm, and a manually-operated device having a sliding connection with and to move said draw-bar longitudinallyandlaterally, to remove the hook of the said draw-bar from the pin, to thereby release the traversing means, substantially as described.

2. In aring-spinning frame, traverse mechanism, a reciprocating hooked draw-bar detachably connected therewith, and provided with a cam-surface, means to manuall7 move the traverse mechanism, and an independent releasing device to disconnect said draw-bar from the traverse mechanism and maintain it disconnected,said device comprising a lever the upturned end of which has a sliding connection with the draw-bar, the said end of the lever engaging the cam-surface to move the draw-bar lon gitndinally, substantially as described.

3. In a ring-spinning frame, traverse meehanism, a reciprocating, hooked draw-bar to actuate it, a cam-block on said har, a lever having thereon a slotted plate, to engage said block and thereafter to disengage the hooked draw-bar from the traverse mechanism, and a manually-operated controlling-bar for said lever, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
